Hi, I was wondering if you can provide me with some guidance regarding RTT. BTW: I read and understood the osgMultipleRenderTargets example very well (hopefully 8)). However, I was wondering if it would be possible to simply it a little for my app.
My application has multiple slave cameras using osgViewer (not composite viewer). Each camera can show the scene using a different sensor mode (i.e thermal, day, nigt-vision, etc). On a per camera basis, I need to render the scene to a texture. Each of those cameras then render their respective image to a simple quad in their own window. The questions is: can I do this without adding a seperate RTT camera for each slave camera? Will enabling RTT for each slave camera and drawing a simple quad in the PostDrawCallback/FinalDrawCallback work (using direct opengl calls)? Do I absolutely need to add another camera in the scene to make RTT work? Maybe if I understood the render-to-texture process in the camera a little better, especially when it starts and when it ends, then I would have a better idea if what I'm trying to is possible. Any help would be appreciated.
